Hello pgsql-novice,
I'm trying to return a set of rows from a stored procedure, but
haven't quite hit on the right syntax. I'm sure this is quite a
trivial question, but all my googling has failed me (and so has
"PostgreSQL: The comprehensive guide to building, programming, and
administering PostgreSQL databases, Second Edition").
My code is:
create table country (
name varchar(100),
alpha_two_code char(2),
alpha_three_code char(3),
numeric_code int,
primary key (numeric_code)
);
create or replace function load_country() returns setof country as
$body$
begin
return query select * from country;
return;
end
$body$
language 'plpgsql';
The problem I have is my function keeps on returning a single column
with the name of the function, rather than something akin to the table
I've defined:
sanzala=# insert into country values('a','b','c',123);
INSERT 0 1
sanzala=# select * from country;
name | alpha_two_code | alpha_three_code | numeric_code
------+----------------+------------------+--------------
a | b | c | 123
(1 row)
sanzala=# select load_country();
load_country
--------------------
(a,"b ","c ",123)
(1 row)
I guess the fault is in "setof country", but I've tried returning
_country, country%rowtype, etc - all with no luck. What am I doing
wrong?
Many thanks for your time,
Marco
